I just got a Bellman Stovetop Steamer earlier this week and it works surprisingly well.
Here's a video I made of me making a latte with it.
The hole on the steamer tip is quite small, and it takes a while to get the milk up to temperature. So it's a little tricky knowing when you've incorporated enough air - if you do the "stretch until body temperature" rule, I've found that you get to much foam for even a cappuccino. But once you get the hang of when to stop stretching and when to roll the milk, you can get really good microfoam with it, as you can see in the video.
It also takes a while to heat up to build enough pressure to create steam, but I use the Mypressi Twist with it, and found that by the time it takes me to get ready to pull my shot on the Twist, the Bellman is all ready to go.
